I have a handful of different swimsuits, but my favorite one, the one I use most often and which I've worn to public beaches and swimming pools, pool parties, out with friends, on vacation, and even when swimming at family gatherings, is pretty unique.

It's a black latex one piece with a zipper in the back to allow access, and a built in dildo which must be inserted to wear it.

Everybody just thinks it's like a swimsuit for racers or something, nobody I've been out swimming with while wearing it has any idea about the dildo or the zipper. Nobody I didn't tell anyway.
